44. HEM^ENASIUS Ashmead, ne^A^ genus. 



(Type, Hemivnasius confasus Ashmead.) 



Aspect of u^nasius Walker and Euryrliopalns Howard, but quite dis- 

 tinct from both in sculpture and in following cliaracters : I'rom /Enasius 

 it differs in punctuation, in the much longer scape and flagellum, the 

 former being only slightly dilated, the longer mesonotum and in vena- 

 tion ; from Euryrhopalus in the broader vertex, antennal characters, 

 and in the quite different venation, brought out in my table. 



I. HEMi^NASIUS CONFUSUS Ashmead, new species. 



Female. — Length, 1 mm. Eobust, black, the head anteriorly from the 

 front ocellus blue; llagellum brown-black, tlie scajie at base and apex 

 yellowish; funicle joints 4 and 6 whitish; tips of tibite and tarsi, 

 except last joint, honey yellow; wings hyaline, dusky or fuliginous at 

 base only, the marginal vein punctiform, the postmarginal vein devel- 

 oped but slender, about two-thirds the length of the sigmal: all veins 

 brown. The head on vertex has some small scattered punctures but 

 anteriorly it is perfectly smooth and polished; the thorax is almost 

 smooth, but with a strong lens one can detect some delicate transverse 

 strife and a few microscopic punctures; abdomen short, broadly oval, 

 smooth and shining.

46. HEMENCYRTUS Ashmead, new genus. 

 (Type, Hemencyrtus herbertii Ashmead.) 



Stature and general appearance of JEncyrtus cecidomyiw Howard, but 

 quite different in sculpture and in venational and antennal characteris 

 tics. The head is scarcely as wide as the thorax between the wings, 

 lenticular, shagreened, but with sparse, distinct, umbilicate punctures 

 on the forehead. The antenuic are 11-jointed, filiform or nearly, and 

 clothed with short, sparse hairs, the joints of the funicle all being a little 

 longer than wide; the club is rather short, scarcely as long as the 

 pedicel and first joint of funicle united, the pedicel being obconical anti 

 hardly twice as long as thick.
